DISK-CLUTCH REVERSER.

Griginal application filed May 28, 1921, Serial No. 473,323. Divided and this application filed August To all cli/tom t may concern t Be it known that I, DAVID C. KLAUsMnYER, a citizen of the United States, and residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and Improved Disk-Clutch Reverser, of which the following specification is a full disclosure.

rIhis invention relates to motion-reversers ofthe type having a plurality of friction disks and is derived from the structure providing tooth-mesh adjustments disclosed by Fig. 4 of my pending applic-ation (of which this is a division) Serial No. 473,323, iiled May 28, 1921, and patented on August 12, i924, No. 1,505,074.

It is, accordingly, an object of this invention to provide a motion-reverser in the nature of a unit in combination with a. shaft freely translatable relativelyV to the unit and in which the operating elements will be mounted (independently in the shaft) on a rotatable sleeve j ournaled at its ends in fixed portions or end-walls of the frame and in which the gears will be very compactly nested and arranged to transmit power through friction clutches of the disk-type mounted on the end portions of the rotatable sleeve; together with an instrumentality for connecting either one or the other of the coaxial gea-rs with the sleeve by means of a compactly mounted manually operative clutch actuator.

In achieving the general objects above noted, this divisional invention seeks also to provide easily operable means for compensating for wear of the teeth of the bevel gears whereby they may be adjusted in position and relationship from time to time so that the pitch-lines of the three gears may be maintained accurately in coincidence and thus promote smooth ruiming in said gears and keep the wear at a minimum.

Other objects and advantages will be in part indicated in the following description and in part rendered apparent therefrom in connection with the annexed drawings.

To enable others skilled in the art so fully to apprehend the underlying features hereof that they may embody the same in the various ways contemplated by this invention, drawings depicting a preferred typical construction have been annexed as a part of Serial No. 731,109.

this disclosure and, in such drawings, like characters of reference denote corre-sponding parts throughout all the views, of

which Fig. 1 is a longitudinal section showing the general assembly of the element-s of this device and of the gear-adjusting means. Fig. 2 is a transverse section taken along a medial of Fig. 1 sho-wing the arrangement of the lever for operating the clutches. Fig. 3 is a section through line 3-3 of Fig. l; certain parts being omitted. Fig. 4 is an end View of the adjustable bearing-cap.

Continuing now by way of an analysis of the herein illustrated examples of this invention, 1 indicates a frame for supporting and positioning the major elements of the device. lhile this frame may be open, it will be formed in the nature of a closed casing in the preferred aspect of this invention, so that the various bearings may be shielded against grit and may be run in a bath of oil or grease. This frame is characteristically provided with means for providing stationary journals for the mounting of the ends of a rotating sleeve which in turn supports two conversely-rotating bevel-gears. A convenient way of achieving that end is illustrated in Figs. 1 and 4, wherein 2 indicates a bearing-cap adjustably mounted on an end-wall of the casting; it being adjustably yet firmly aiiixed thereto by screws 3 and 3a.

The casing l is provided with a bearing 6 located intermediate the ends of the rotatable sleeve 21 and this receives a shaft 7 having affixed to its: inner end a bevel-gear 8 which, accordingly, faces the rotatable sleeve 21 substantially midway its ends. Mounted on the journals -4 and 5, are two bevel-gears 9 and 10 which are in mesh with the bevel-gear 8, as shown byFig. 1. As will be understood, the effect of this intermesh is to urge the gears 9 and 10 away from the axis 2-2 of the shaft 7 and, in order to limit this movement, suitable thrustlimiting means are provided adjacent of outer faces of the gears 9 and 10. These gears are rotatably, as well as translatably, mounted on the journal portions 4 and 5 (as for example through the agency of thev brass bushings 11) so as freely to admit of lateral movement against the said thrust bearing.

In the course of time, suficient Wear will take place to impair the original precision ofthe interinesh and, therefore, provision is madefor adjusting the gears toward the axis line 2-2 To that end, the cap 2 is telescoped in the end of the stationary frame 1 so that it may be adjusted towards the axis lineQf-Q a thrustbearing 77 (preferably of the ball type) being interposed for the purpose of decreasing friction and Wear. Inasmuch as both the gears 9 1 and 10 are journaled enga singleelement, they admit of beine' ,held very closely Vin an accurate coaxia relation; there being no intervening loose. elements to impair the precision of the filelist :.1 i

The gear, Q, fis ofsmalldiameter and its horeiscomparatively small so that, While Vperm itting thegear 8 to be set close to the centralaxisof spindle, it will nevertheless run ,smoothlyv While such gear may haveits guter portion configurated in any manner appropriate to the type of. clutch usted, it will be noted that theexample illustratedv presents a` very desirable characteristict o. Wit, it merely. has a simple disklike flange 14 Aof small diameter formed on its end. f

f :flliisflange M .may be regarded as the malepinemherof the clutch or, as a matter of nomenclature, vthe clutch may be .referred to,as,consisting olf the various movable and adjustable. ,elements comprising the separate-,unit iioyvte bedescribed. This ydevice comprises a body `proper 15 having a hub 16 f inthe fornrof asleeve. A v

The. general object of motion reversers of the sort-in view, to .enable motion to be transmitted from a shaft 7 to another shaft arranged at an. angle thereto;l .usually in the same axial planet-herewith and usually also aty rightangles thereto, but not necessarily so-. The shaft 20, however, must admitefbeing translated iny anaxial direction relative-tothe shaft 7 Without any break in the connection l,but otherwise accurately preserving AKthe spatial relations between the tyvp.,. The shaftZO is, accordingly so journ aled (either directly or indirectly) vvith respectto the frame that the aforesaid relation will be preserved, and also sro connected (either directly or indirectly) with the clutch as to preserve the driving relation in all of vits positions. The former may be achieved indirectlyby resorting to an intervening sleeve arranged, on. the one hand, to serve as a bearing for the shaft .and being,

on the other hand, ,itself journaled in the end Walls of the casing. Thus, as shown by Fig. .1 kthe elongated tubular sleeve y21 is splined to the shaft means oft-he key 22l andis also (as by means ofbearings 77) j ournaled `at its ends Within a fixture or part of the casing. These bearings 77 are located near the ends of the fixed sleeve, as shown,

so as: to ensure accuracy in alignment and, in case a. closed casing be used, the rotary sleeve preferably will extend into Openings 24 in either the adjustable cap'Q- or directly in the end-walls 25 thereof to make provision for rdust-guards 26 in the nature of pacli'ing adapted to prevent undue leakage of the lubricant. The end-portion 2 7 of the rotary sleeve may lalso be journaled directly in said openings if desired to ensure the alignment and, yto restrict the end-play, nut 78 (screw threadedtothe rotary sleeve) bears against theclutch member 16 through the interposed ball bearing 77 thereby keeping the rotary sleeve, in placeand providing a slightlloat. The thrust-bearing 77 may be of the form shown in Fig, 1 and Wear may be compensated for by aturning of the screws 8 and 3a. As shown 1 the ball bearing 77 carries -both the thrust and the side. strainsz and adjustment is also atlordedby a collar 7 8 screw-'threaded tothe end-pertion of the sleeve and located in a socket in the capf. i

As has been stated, this invention vadmirably admits of the use o-f dislfr-cli'itches,

as for example of the construction shown..

preferably in'a notch 52 so as to prohibit any rotation of the shoe relative to the clutch-member 15.

l' lhe thrust resulting from the pressureof the shoeis, cn the other sideof the flange 14, resistedby an annular member which, for ease of assembly, vmay be made, as shown, by F 3, of tvvo half-rings 53 and '54 hinged together by the pin 55 to form a Vcomplete circle. These half rings have flanges 5,7 that areinteriorly screw-threaded, als indicated by 58, soas to be adjustably aflixed to the' flange 18 ot' `the clutch-member 15., -A screiv serves to bind theparts securely in place,

as will Abe understood. t

lt will be noted that the clutch-parts are capable of a slight float or movei'nent ,as a unit in an axial directionso that a degree of self-adjustment in conformity ivithgthe position of the flange'14, is thereby `profvided.; thus `avoi'ding the d'ra-gfsometimes exhibited by faulty clutch designs.'

To operate theclutches, a and-lever GO (Fig. is aiiixed to' a stub-shaft 61 jouir-A naled in a boss 62 provided by the frame or casing. To the innery end of suoli shaft 61,

is affixed a lever 63 having a. shoe 64 pivoted to its end and seated in a recess 68 provided by an enlargement 66 on the shift-rod 65. The latter is shown supported at its ends in the end-walls of the frame and it carries ay member 67 having a slot 69 engaging a flange 70 projecting from a conical leveractuator 7l which, when moved laterally, may engage rolls 72 on the ends of the levers and operate the clutches, as will be perceived.

The simplicity and compactness of the above revealed organization is, especially noteworthy and it will be seen that it overcomes certain troublesome features of previous designs and is rugged and not likely to become disarranged in use and may be assembled readily and subsequently adjusted as occasion demands to maintain accuracy and smoothness of action.

Without further analysis, the foregoing will so fully reveal the gist of this invention that others can, by applying current knowledge, readily adapt it for various utilizations without omitting certain features that, from the standpoint of the prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention, and therefore such adaptations should be and are intended to be comprehended within the meaning and range of equivalency of the following claims.
